On top of only working with ESXi (ESX works but isn't supported by the BU), you will likely only get this to work on Intel processors. Also note that VMware support technically wasn't added until 8.0(2).

Trying to get CUCM to work on AMD system is a nightmare, which I haven't realized until I was faced with one.

I can't say much about CUCM 8, however in case of CUCM 7.x, I did a workaround this to get it to work on a quad-core AMD system by building the server on Intel machine and then transfering the vm-ware image to the AMD system. This should work for most of the functionality, however there are still some items you'll have problems with, such as you won't be able to play with MOH, as the server won't register on AMD machine for some reason.

I got 8.0(1) to run in Workstation fine, but then tried to upgrade to 8.0(2), and it failed.

I then resorted to building myself a little ESXi setup, and migrating the VM using a converter. Still had some problems, so then went to a Cisco-UCS spec VM (6GB, 2CPU, SCSI HDD at 0:0) and all was well. At this stage I'm wondering whether it was the switch to ESXi, the VM spec changes, or both that were required.

Please check SCSI disks are at least 72GB in size and are located at 0:0 (and 0:1 in a two disk config) in machine settings.

The virtual host is formatting the HD into several different partitions leaving only 60G of usable space. I realize that this is a Cisco related forum I will also ask this on vmware.com forum but does anyone know of a way to get the datastore to format differently?

Found a sobering post today on another forum. User complained about another user 'hijacking' his thread. He said it wasn't proper ettiquette. Guess that's what I've done here and several other times I won't do that anymore my apologies to anyone I may have offended.

I know I said I wouldn't hijack posts anymore. I feel this is relevant and may help someone who is searching and may be having the same problems I was.

I searched this forum for CUCM_7500_user_v1.0_vmv7.ova with no results. I was finally was able to create a VM CUCM 8.0(1) using this template. From the Vshpere Client under the file options menu is the option to 'Deploy OVF template'. Choose it it's intuitive from there. Then you can install CUCM on the VM. Make sure to check the box 'connect DVD at startup' and check the box under options to 'boot from BIOS' then boot off the install disk.

You can find the template on cisco.com on the download software pages for CUCM.

I will also go back and try to create one using the spec's that are in this thread.

I did the same as you mentioned created a VM CUCM 8.0(1) using this template but still have the same error that the installation has failed. It doesn't matter if I am doing it manual or via the template and I do have a ESXI server.

I still see the

Error not sure if this is related but did anyone got it to work with this error?

Sounds like you did you the .ova template to create your vm machine correct? It's difficult to see the screen shot (maybe you should attach it) that you posted but it doesn't appear to show the failure only that it's in the hardware detection phase of the install. Is that correct?

Also I would post more specifics about your platform for everyone to see.

I have a quite old MCS 7835I (2GB RAM, 2 x 72 GB Disk and Intel Xeon CPU 3.4 Mhz), which I use for Lab purposes.

Up to CUCM V7.1 this one worked fine. CUCM V8 does not support this Hardware natively (I assume because of the Disks), therefore I am trying to make it working as guest system under ESXi 4.1 and the OVF Template from CCO.

I splitted up the RAID which brings 135 GB Disk space in the datastore of VMWare and I´ve selected "Thin Provisioning" due to limited disk space.

5* for you Marcus. Thanks for the screenshot. I was able to get this working on VMWare Server. The keys to getting it to work were using RHEL 4 and 80GB Dual HDD. Got errors when either of those wasn't configured.

The solution to fix your issue is simple as I was just experiencing the same problem. The problem you are having is with the SCSI controller that VMware defaults to use when creating new VMs. You need to change your SCSI controller over to an LSI Logic SAS controller under the CUCM 8.x VM. I quickly made a scratch VM to show you, but the default controller type is paravirtualize. Once I changed my controller over it worked like cake.

I am still in the installation process of vmware 7 w/ cucm 8. my cisco router is configured w/ an Ip 192.168.1.2 and its gtwy is .1 . when I give the CM an ip of 192.168.1.100/24 gtwy .1 and the NTP 192.168.1.2/24 still get the same message of the network is unreachable so I hit ignore then was presented w/ NTP config I put in Ip address 192.168.1.2 and I hit test I get an error Inaccessible..I could not pass beyond this point.. so I am thinking that my virtual nic is not communication w/ router. anyone that help I appreciated.

Thanks Anas ... the problem here is that I have no visibility to the Internet for me to put a public ip. I tried and still no go . I need to get VMWARE to see my router for me to get out to the Net . still struggling w/ it. I also attached some of screen shot on the same forum. " cucm 8 on vm 7.1".

I have gotten this to work on a AMD Processor by first loading it on a Intel based PC in VMware Server 2, once completed I used the VMware Standalone Converter to convert the machine. I then copied to my AMD based ESXi 4.1 Server.
